Hi Ling Miao Thank you for your reply.
In the process of using Doris on ES, there will be a table of ES, but the corresponding two sub tables have different table structures. This problem can be solved by building different Doris external table through different es sub tables, but the external table of Doris will increase geometrically. This is difficult to manage because of too much external tables. So I want to ask if there is any better way. For example, can partitioning and buckets solve this problem ? Or is there a better way ?

A table can only have one table structure at a time. But what I am more puzzled is, under what circumstances will the concept of sub-tables be used in business requirements. Does it mean that ES supports one table but has two different table structures? Is it possible to treat these two sub-tables directly as the two external tables of Doris?

Does Doris have the function of sub table ? I didn't find an introduction to Doris's sub table function. IF not, What I want to know is can Doris bucket redefine the table structure ? Suppose that a table of ES has two sub tables corresponding to two buckets of Doris, but the table structures of the two sub tables of ES are different, can the two buckets of Doris also define different table structures? Or is there a corresponding solution in this case ?
